93958149 ÷ 661 
We want to divide 93958149 by 661.

Step 1:
If we divide 9 by 661, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 661

Moving on to step 2:
The number 661 fits into 93 0 times, leaving a remainder of 93.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 93, we end up with 93.
Append the next digit (9) from the dividend to 93 and continue with: 939 / 661

Going ahead to step 3:
If we divide 939 by 661, we get 1 and a remainder of 278.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 661 away from 939, we end up with 278.
Fetch the next digit (5) from the dividend, attach it to 278 and continue: 2785 / 661

On to step 4:
661 can be fit into 2785 4 times, resulting in a remainder of 141.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 2644 from 2785, we get 141.
Take the next digit (8) from the dividend and append it to 141, then repeat: 1418 / 661

Let's proceed to step 5:
If we divide 1418 by 661, we get 2 and a remainder of 96.
The next digit of our result is 2. 
Result so far: 142.0
The remainder is 96 after subtracting 1322 from 1418.
Fetch the next digit (1) from the dividend, attach it to 96 and continue: 961 / 661

Step 6:
661 goes into 961 1 times with a remainder of 300.
Write down 1 as next digit of the result. 
Result so far: 1421.0
If we take 661 away from 961, we end up with 300.
Take the next digit (4) from the dividend and append it to 300, then repeat: 3004 / 661

Moving on to step 7:
661 can be fit into 3004 4 times, resulting in a remainder of 360.
Write down 4 as next digit of the result. 
Result so far: 14214.0
Subtracting 2644 from 3004 leaves us with 360.
Bring next digit (9) of the dividend behind the 360 and repeat the process: 3609 / 661

Step 8:
3609 divided by 661 is 5 with a remainder of 304.
Use 5 as the next digit of our solution. 
Result so far: 142145.0
Subtracting 3305 from 3609 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 9:
If we divide 3040 by 661, we get 4 and a remainder of 396.
The number 4 becomes the next digit in our result. 
Result so far: 142145.4
If we subtract 2644 from 3040, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 10:
The number 661 fits into 3960 5 times, leaving a remainder of 655.
The number 5 becomes the next digit in our result. 
Result so far: 142145.45
If we take 3305 away from 3960, we end up with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Moving on to step 11:
661 can be fit into 6550 9 times, resulting in a remainder of 601.
Put 9 as the next digit of the answer. 
Result so far: 142145.459
Deduct 5949 from 6550 and we're left with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

On to step 12:
6010 divided by 661 is 9 with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 142145.4599
Subtract 5949 from 6010 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

In conclusion, the division gives 142145.4599 with a balance of 0.00061.
